I suspect that there's an extraneous blank line in the incoming Internet message

If this was working before -- that is, no base64 encoded text in the received message body -- and it's not working now because the received message body is encoded, well, this can happen in a couple of ways.

The first way -- if the incoming message has an arbitrary line of text embedded in the Internet message headers, then the Domino SMTP server may not be able to determine where the headers end and the body begins.

For example:

To: me@mydomain.com

From: you@yourdomain.com

Subject: messed up message

Date: Mon, 16 Mar 2015 20:57:00 -0400

MIME-Version: 1.0

This is a line of text that is not a header

Content-type: text/plain

This is the text in the body.

When the Domino SMTP server parses the line 'This is a line....', it makes the best of a bad situation and treats it as the first line of the body. This would be the resultant body in the received message:

This is a line of text that is not a header

Content-type: text/plain

This is the text in the body.

The second way -- and this is what I think is happening in your scenario -- is when there's a blank line incorrectly inserted before the end of the message headers, like so:

To: me@mydomain.com

From: you@yourdomain.com

Subject: messed up message

Date: Mon, 16 Mar 2015 20:57:00 -0400

MIME-Version: 1.0

Content-type: text/plain

Content-transfer-encoding: base64

Note the blank line after the 'MIME-Version' header. This message will result in this received message body--

Content-type: text/plain

Content-transfer-encoding: base64

VGhpcyBpcyB0aGUgdGV4dCBpbiB0aGUgYm9keS4N

--rather than the expected, properly decoded body:

This is the text in the body.

If you have access to the Domino server:

If you send another test message and capture the incoming message stream and this is the problem, you should be able to see the extraneous blank line.

Capture incoming Internet message streams by using an ini setting and then telling the Domino SMTP server to refresh its configuration settings.

At the Domino server console:

set config SMTPSaveImportErrors=2

tell smtp update config

The SMTP server will log a message on the console when it saves incoming message streams. Something like this--

RFC822 message stream saved to C:\tmp\STnnnnnn.TMP

--where C:\tmp is the system temp directory (on a Windows machine) and 'nnnnnn' is a random six digit integer.

Good luck.
